A new venture team is a particular type of top management team neglected by the literature. This study investigated the effects of team inputs and processes on team members' perceptions of team viability and satisfaction in nascent ventures. These outcomes are important as they may be antecedents of team perseverance. The study of 51 new venture teams showed that the presence of a distinct leader was positively related to team satisfaction, while member diversity in educational backgrounds was positively related to perceived team viability. Intrateam processes of social integration and open communication were positively related to both perceived team viability and member satisfaction. Copyright © 2006 John Wiley & Sons, Ltd.
